Quick Summary

The Beaverkill and Willowemoc are among the more practical Catskill wade choices today, though the Beaverkill still has enough volume to require careful footing. USGS showed the Beaverkill near Cooks Falls around 741 cfs and steady to slightly falling. Afternoon water reached about 60 F, so the hatch window is useful but anglers should keep an eye on temperature if fishing slower water late.

Weather

Livingston Manor was mostly sunny near 75 F late today with southwest wind around 8 mph. Tonight is forecast mostly cloudy, which should keep the evening from getting too bright and may help olives, caddis, and spinners.

River Notes

The freestones are in better relative shape than the higher tailwater edges, but they are not low-water creeks. Focus on riffle margins, inside bends, soft pockets behind structure, and broad tailouts where trout can feed without sitting in the hardest current. If the water warms quickly, shift toward faster, oxygenated water and stop targeting trout if readings approach stressful levels.

Hatch Activity

Gray Fox12-14Can overlap with March Brown activity
Blue Quill16-18Useful smaller mayfly option

Caddis14-18Carry adults, pupa, and soft hackles

Recommended Flies

Tactics

Use nymphs or wet flies through riffles and seams until bugs are visible. During hatch activity, move to single dries or a dry with an emerger and target fish you can see feeding. Keep wading conservative; crossing heavy freestone current is not worth it when edge water is producing.
